DETAILED DESCRIPTION

Technical solutions in implementations of the present disclosure will bedescribed below with reference to the drawings in implementations of thepresent disclosure. It is apparent that the implementations describedare just some implementations of the present disclosure, but not allimplementations of the present disclosure. With respect to theimplementations of the present disclosure, all other implementationsachieved by a person of ordinary skill in the art without paying aninventive effort are within the protection scope of the presentdisclosure.

Implementations of the present disclosure may be applied to variouscommunication systems, such as a Global System of Mobile (GSM)communication system, a Code Division Multiple Access (CDMA) system, aWideband Code Division Multiple Access (WCDMA) system, a General PacketRadio Service (GPRS), a Long Term Evolution (LTE) system, an AdvancedLong Term Evolution (LTE-A) system, a New Radio (NR) system, an NRsystem evolution system, a LTE-based access to unlicensed spectrum(LTE-U) system, an NR-based access to unlicensed spectrum (NR-U) system,a Universal Mobile Telecommunications System (UMTS), a Wireless LocalArea Network (WLAN), Wireless Fidelity (WiFi), a next generationcommunication system, or other communication systems.

Generally speaking, the number of connections supported by a traditionalcommunication system is limited and easy to implement. However, withdevelopment of the communication technology, mobile communicationsystems will not only support traditional communication, but alsosupport, for example, Device to Device (D2D) communication, Machine toMachine (M2M) communication, Machine Type Communication (MTC), orVehicle to Vehicle (V2V) communication.

The applied spectrum is not limited in the implementations of thepresent disclosure. For example, the implementations of the presentdisclosure may be applied to a licensed spectrum, or an unlicensedspectrum.

Illustratively, a communication system 100 to which an implementation ofthe present disclosure is applied is shown in FIG. 1 . The communicationsystem 100 may include a network device 110, and the network device 110may be a device that communicates with a terminal device 120 (orreferred to as a communication terminal, or a terminal).

Optionally, the communication system 100 may include other networkentities such as a network controller, and a mobile management entity,which is not limited in implementations of the present disclosure.

It should be understood that, a device with a communication function ina network/system in the implementations of the present disclosure may bereferred to as a communication device. The communication system 100shown in FIG. 1 is taken as an example, the communication device mayinclude a network device 110 and a terminal device 120 which havecommunication functions, and the network device 110 and the terminaldevice 120 may be the specific devices described above, which will notbe described herein again. The communication device may also includeother devices in the communication system 100, such as a networkcontroller, a mobile management entity, and other network entities,which is not limited in the implementations of the present disclosure.

The implementations of the present disclosure describe variousimplementations in combination with a terminal device and a networkdevice. Herein the terminal device may also be referred to as a UserEquipment (UE), an access terminal, a subscriber unit, a subscriberstation, a mobile station, a rover station, a remote station, a remoteterminal, a mobile device, a user terminal, a terminal, a wirelesscommunication device, a user agent, or a user device, etc. The terminaldevice may be a station (ST) in the WLAN, or may be a cellular phone, acordless phone, a Session Initiation Protocol (SIP) phone, a WirelessLocal Loop (WLL) station, a Personal Digital Assistant (PDA), a handhelddevice or a computing device with a wireless communication function, orother processing devices connected to a wireless modem, avehicle-mounted device, a wearable device, or a terminal device in anext generation communication system, such as a terminal device in an NRnetwork or a terminal device in a future evolved Public Land MobileNetwork (PLMN).

By way of example and not limitation, in the implementations of thepresent disclosure, the terminal device may be a wearable device. Thewearable device may also be called a wearable intelligent device, whichis a general term of wearable devices designed intelligently anddeveloped on daily wear using wearable technology, such as glasses,gloves, a watch, clothing and shoes. The wearable device is a portabledevice that is worn directly on a body or integrated into a user'sclothes or accessories. The wearable device not only is a hardwaredevice, but also implements powerful functions through software support,data interaction and cloud interaction. Generalized wearable intelligentdevice include a device with full features, a large size, and full orpartial functions which may be implemented without relying on a smartphone, for example, a smart watch or smart glasses, as well as a devicethat is only focused on a certain application function and needs to becooperated with other devices such as a smart phone, for example, asmart bracelet and a smart jewelry for various physical signobservations.

The network device may be a device for communicating with a mobiledevice, or may be an Access Point (AP) in the WLAN, or a BaseTransceiver Station (BTS) in GSM or CDMA, or may be a NodeB (NB) inWCDMA, or an Evolutional Node B (eNB or eNodeB) in Long Term Evolution(LTE), or a relay station or an access point, or a vehicle-mounteddevice, a wearable device, a network device (gNB) in the NR network, ora network device in the future evolved PLMN network.

In the implementations of the present disclosure, the network deviceprovides services for a cell, and the terminal device communicates withthe network device through transmission resources (e.g., frequencydomain resources or spectrum resources) used by the cell. The cell maybe a cell corresponding to the network device (e.g., a base station),the cell may belong to a macro base station, or may belong to a basestation corresponding to a Small cell which here may include a Metrocell, a Micro cell, a Pico cell, a Femto cell, etc. These small cellshave features of small coverage and low transmission power, and aresuitable for providing high-speed data transmission services.

It should be understood that in the implementations of the presentdisclosure the NR may be deployed independently. In order to reduce airinterface signaling, quickly resume radio connection and quickly resumedata service in a 5G network environment, a new Radio Resource Control(RRC) state, namely an RRC_INACTIVE state, is defined. This state isdifferent from RRC_IDLE and RRC_CONNECTED states.

In RRC_IDLE state: mobility is UE-based cell selection and reselection,paging is initiated by a Core Network (CN), and a paging area isconfigured by the CN. There is no UE Access Stratum (AS) context and noRRC connection at a base station side.

In RRC_CONNECTED state: there is an RRC connection, and there is UE AScontext on the base station and the UE. Location of the UE known by thenetwork device is a location on a specific cell level. The mobility iscontrolled by the network device. Unicast data may be transmittedbetween the UE and the base station.

In RRC_INACTIVE state: mobility is UE-based cell selection andreselection, there is a connection between a CN and an NR, there is UEAS context on a certain base station, paging is triggered by a RadioAccess Network (RAN), a RAN-based paging area is managed by the RAN, andthe location of the UE known by the network device is a location on aRAN-based paging area level.

The network device may control a state transition of the UE. Forexample, as shown in FIG. 2 , the UE in the RRC_CONNECTED state mayenter the RRC_IDLE state by releasing the RRC connection; the UE in theRRC_IDLE state may enter the RRC_CONNECTED state by establishing an RRCconnection; the UE in the RRC_CONNECTED state may enter the RRC_INACTIVEstate by releasing with suspend the RRC connection; the UE in theRRC_INACTIVE state may enter the RRC_CONNECTED state by resuming the RRCconnection, or enter the RRC_IDLE state by releasing the RRC connection.

It should be noted that the UE in the RRC_INACTIVE state autonomouslyreturns to the idle state under the following situations:

-   -   when receiving an initial paging message from a CN;    -   when an RRC resume request is initiated, a timer T319 is        started, and if the timer expires;    -   when integrity protection verification of a contention-based        random access message 4 (MSG4) fails;    -   when a cell is reselected to another Radio Access Technology        (RAT);    -   when entering a state of camping on any cell.

Characteristics of the RRC_INACTIVE state:

-   -   connection between a RAN and a CN is retained;    -   UE AS context is stored in the UE and at least one gNB;    -   UE is reachable to a RAN side, and relevant parameters are        configured by the RAN;    -   Movement of UE in a RAN notification area (RNA) configured by        the RAN is not needed to notify a network side (a core network        device), but it is needed to notify the network side (the core        network device) when the UE moves out of the RNA;    -   Movement of UE in the RNA is based on a cell selection and        reselection manner.

It should be noted that the RNA may be specifically shown in FIG. 3 ,and in the RNA shown in FIG. 3 , it is not needed to notify the networkside when the UE moves between base station 1 and base station 5, but itis needed to notify the network side when the UE moves to base station 6or base station 7.

When the UE is in the RRC_INACTIVE state, the network device configuresconfiguration parameters of RRC_INACTIVE to the UE through RRC Releasededicated signaling, for example, configures an RNA which is used forcontrolling an area where the UE performs cell selection and reselectionin the inactive state and is also an initial paging range area of theRAN.

The movement of UE in the RNA area is not needed to notify the networkside, and complies with mobility behaviors in the idle state, that is,the principle of cell selection and reselection. When the UE moves outof the paging area configured by the RAN, the UE is triggered to resumean RRC connection and reacquire a paging area configured by the RAN.When downlink data for the UE arrives, a gNB which retains a connectionbetween the RAN and the CN for the UE will trigger all cells in the RANpaging area to send a paging message to the UE, so that the UE in theINACTIVE state can resume the RRC connection and receive data. The UE inthe INACTIVE state is configured with a RAN paging area, to ensurereachability of the UE in this area, the UE needs to update its locationperiodically according to a period configured by the network.

Therefore, a scenario in which the UE is triggered to perform RNA updateinclude a scenario in which a RAN Notification Area Update (RNAU) timerexpires or the UE moves to an area outside the RNA.

It should be understood that the implementations of the presentdisclosure may be applied to an NR Carrier Aggregation (CA) scenario,that is, by jointly scheduling and using resources on multiple ComponentCarriers (CCs), the NR system may support a larger bandwidth to becapable of achieving a higher system peak rate. As shown in FIG. 4 , anaggregation of discontinuous carriers may be achieved, and two componentcarriers are carrier A and carrier B, respectively, which arediscontinuous carriers, each occupies 20 MHz bandwidth, the carriers Aand B occupy 40 MHz bandwidth in total. Or an aggregation of continuouscarriers may be achieved, five component carriers are carrier 1 tocarrier 5, respectively, and carrier 1 to carrier 5 are continuouscarriers, each carrier occupies 20 MHz bandwidth, the five componentcarriers occupy 100 MHz bandwidth in total.

In the NR CA, there is only one Primary Cell Component (PCC), and thePCC provides RRC signaling connection, Non-Access Stratum (NAS)functions, security and so on. A Physical Uplink Control Channel (PUCCH)exists only on the PCC. Secondary Cell Component (SCC) only providesextra wireless resources. Both the PCC and the SCC are called servingcells. The standard also specifies that a maximum number of aggregatedcarriers is 5, that is, a maximum bandwidth after aggregation is 100MHZ, and the aggregated carriers belong to the same base station. Allaggregated carriers use the same cell radio network temporary identity(C-RNTI) to be implemented in the base station ensures that the C-RNTIdoes not collide in a cell where each carrier is located. Sinceasymmetric carrier aggregation and symmetric carrier aggregation aresupported, it is required that the aggregated carrier must havedownlink, and may have no uplink. In addition, it is certain that thereare a Physical Downlink Control Channel (PDCCH) and PUCCH of the cellfor the primary carrier cell, and only the primary carrier cell has thePUCCH, and other secondary carrier cells may have a PDCCH.

The SCell is configured through RRC dedicated signaling, and an initialconfiguration state is an inactive state, in which data cannot be sentand received. Then after the SCell is activated through a MAC CE, datacan be sent and received. In terms of delay between the SCellconfiguration and activation, this architecture is not an optimal one.In addition, this delay reduces efficiency of CA usage and wirelessresources, especially in a small cell deployment scenario. In a densesmall cell deployment scenario, signaling load of each Scell is alsovery large, especially when each SCell needs to be configuredseparately. Therefore, the current CA architecture introduces extradelay, which limits the CA usage and reduces a gain of CA load sharing.

It should be understood that the implementations of the presentdisclosure may be applied to Dual Connectivity (DC) which may also bereferred to an MR-DC scenario.

It should be noted that the MR-DC may include (LTE NR DC, EN-DC), (NReLTE DC, NE-DC), (5GC eLTE NR DC, 5GC-EN-DC) and NR DC, wherein, in theEN-DC an LTE node serves as an MN node and an NR node serves as an SNnode, to connect with an EPC core network. In the NE-DC, an NR nodeserves as an MN node, and an eLTE node serves as an SN node, to connectwith a 5GC. In the 5GC-EN-DC, an eLTE serves as an MN node and an NRnode serves as an SN node, to connect with a 5GC. In the NR DC, an NRnode serves as an MN node and an NR node is an SN node, to connect witha 5GC.

For example, a network architecture of the EN-DC may be as shown in FIG.5 , in which an eNB serves as an MN node and a gNB serves as an SN node,and the eNB is connected with a Mobility Management Entity (MME) orServing Gateway (S-GW) through an S1 interface, the gNB is connectedwith the MME or S-GW through an S1-U interface (a user side S1interface), two eNBs are connected through an X2 interface, two gNBs areconnected through an X2-U interface (a user side X2 interface), and theeNB and gNB are connected through an X2 interface. The eNB mainlyrealizes an RRC control function and a control plane function to the CN,and the gNB may configure auxiliary signaling, such as Signaling RadioBearer 3 (SRB 3), which mainly provides data transmission function.

Regardless of the configuration for the CA or the configuration for theMR-DC, it is needed to reduce the delay between SCell configuration andactivation and the delay between SCG configuration and activation, so asto meet increase of cell capacity especially in the small celldeployment scenario.

However, in the 5G NR, neither the configuration for the CA nor theconfiguration for the MR-DC considers optimization of the delay betweenSCell configuration and activation and the delay between SCGconfiguration and activation. However, the 5G cells are mostly coveredby high frequency small cells, so it is necessary to reduce the delaybetween SCell configuration and activation and the delay between SCGconfiguration and activation. In addition, in the 5G NR, an RRC_INACTIVEstate is introduced into the RRC state of the terminal device inaddition to the RRC_IDLE state and RRC_CONNECTED state. In theRRC_INACTIVE state, it is also needed to reduce the delay between SCellconfiguration and activation and the delay between SCG configuration andactivation, so as to meet increase of cell capacity especially in thesmall cell deployment scenario.

FIG. 6 is a schematic flowchart of a wireless communication method 200according to an implementation of the present disclosure. As shown inthe FIG. 6 , the method 200 may include the following acts S210-S230.

In S210, a network device sends first configuration information to aterminal device, wherein the first configuration information is used forindicating a terminal device in an idle state and/or an inactive stateto perform cell measurement, and the first configuration informationincludes first measurement information for a first network and/or secondmeasurement information for a second network, and wherein the terminaldevice is in the idle state or the inactive state.

In S220, the terminal device receives the first configurationinformation sent by the network device.

In S230, the terminal device performs cell measurement according to thefirst configuration information.

Optionally, the network device may send the first configurationinformation through RRC dedicated signaling or system broadcastinformation.

For example, the RRC dedicated signaling is RRC Release information.

Optionally, the first network is an E-UTRAN and the second network is anNR.

It should be noted that when the method 200 is applied to the MR-DCscenario, the first configuration information includes both firstmeasurement information for an E-UTRAN and second measurementinformation for an NR, when the method 200 is applied to an LTE network,the first configuration information includes the first measurementinformation for the E-UTRAN, and when the method 200 is applied to an NRnetwork, the first configuration information includes the secondmeasurement information for the NR.

Optionally, in an implementation of the present disclosure, the networkdevice may further configure a first timer, and the first timer is usedfor controlling validity of the first configuration information. Forexample, the terminal device receives second configuration informationfor configuring the first timer sent by the network device. That is, thefirst timer is started when the first configuration information isreceived, and the first configuration information is released when thefirst timer expires or stops.

It should be noted that the first timer is valid before expiration, andthe first timer is invalid after expiration.

Optionally, the network device may send the second configurationinformation through RRC dedicated signaling or system broadcastinformation.

Optionally, when the network device sends the first configurationinformation through the RRC dedicated signaling, the terminal devicereceives the second configuration information for configuring the firsttimer sent by the network device.

It should be noted that the terminal device may acquire relevantconfiguration of the first timer and then receive the firstconfiguration information.

Optionally, in an implementation of the present disclosure, the networkdevice may further configure a filter coefficient. For example, theterminal device receives third configuration information sent by thenetwork device, and the third configuration information is used forconfiguring a filter coefficient for the first configurationinformation, or the third configuration information is used forconfiguring a filter coefficient for each frequency.

Optionally, the network device may send the third configurationinformation through RRC dedicated signaling or system broadcastinformation.

Therefore, in the implementation of the present disclosure, the networkdevice may indicate the terminal device in an idle state and/or inactivestate to perform cell measurement through the first configurationinformation, and the terminal device in the idle state or inactive statemay perform cell measurement according to the first configurationinformation. That is, the terminal device may perform cell measurementin the idle state or inactive state, and after entering a connectedstate, the terminal device reports a measurement result, to assist thenetwork device to configure a secondary cell and/or secondary cell groupin CA, and/or to assist the network device to multi-radio accesstechnology dual connectivity, thereby rapid activation or inactivationof the secondary cell and/or secondary cell group may be achieved.

Optionally, as example one, the validity area range of the measurementconfiguration is a cell list, and each cell in the cell list isidentified by a cell ID. If a cell ID acquired through system broadcastinformation of a first cell is not included in the cell list, and thefirst cell is a cell to which the terminal device is handed over throughcell reselection, the terminal device may perform one of the followingoperations:

-   -   stopping the first timer and releasing the first configuration        information;    -   stopping measurement for the first configuration information,        retaining the first configuration information, and if the        terminal device returns to a cell range in the cell list before        the first timer expires, restarting measurement for the first        configuration information;    -   stopping measurement for the first configuration information,        suspending the first timer, and retaining the first        configuration information, and if the terminal device returns to        the cell range in the cell list, starting the first timer, and        restarting measurement for the first configuration information.
